An investigation into the sampling bias of Argo profiling floats in the Southern Ocean
Numerous Argo floats (approximately 3800 floats) have been deployed in the world's oceans to gather hydrographic and biogeochemical data from the upper 2000 m. However, limited research has been done on the spatial and temporal distribution and potential sampling bias of Argo profiling floats …

Downstream evolution of ocean properties and associated fluxes in the Greater Agulhas Current System: Ad hoc Argo experiments and modeling
… of the Agulhas Current was investigated using Argo floats, in combination with output from ocean general circulation reanalysis models. Two dedicated experiments were undertaken in April and July 2013, whereby eight floats were deployed within two separate cyclonic eddies. Floats were set to …

Machine Learning for Improvement of Ocean Data Resolution for Weather Forecasting and Climatological Research
… in-situ point ocean data (e.g. ARGO Floats) and Low-Quality/High-Coverage Satellite ocean Data (e.g. HYCOM, MODIS-Aqua, G-COM) and generated high resolution data with a RMSE of 0.58◦C over the Atlantic Ocean.The second part of the work a novel GNN algorithm was implemented on the …

Combining altimetry and hydrography with inverse methods
… The inverse has been applied to simulated Argo floats and satellite altimetry tracks in the Ocean Circulation and climate model (OCCAM). The Bernoulli inverse method predicts the SSH by finding geostrophic streamlines along which the Bernoulli function is conserved. These streamlines are …

Applying statistical analysis and machine learning to improve the Ice Sensing Algorithm
… detection of sea ice is a major problem faced by Argo floats operating in polar regions. In these areas, the presence of sea ice threatens to damage or destroy floats in the event of an impact at the surface. While methods have been proposed and implemented to combat this danger, the most …

Study On the Basin Scale Salt Exchange In the Indian Ocean Using Satellite Observations and Model Simulations
… outputs and salinity derived from satellites and Argo floats to understand the freshwater and salt transport dynamics in the Indian Ocean. Salt advection in the top 5 m layer using the 1/12° high resolution HYbrid Coordinate Ocean Model (HYCOM) during 2003-06 showed that Ekman drift is more …

Upper Ocean Transport Variability in the Subtropical North Atlantic
… sections of the Atlantic using T/S data from Argo floats and the Line W array from 2002 to 2007. Combining these data with an estimate of the barotropic velocity yields accurate values of the interior geostrophic transport above 1000 dbar. Close to the western boundary, where errors incurred …

Investigating the sensitivity of one-dimensional turbulence schemes in the sub-Antarctic Southern Ocean
… the vertical turbulent state with data such as ARGO profiles. It was further found that for a single reanalysis, the turbulence schemes had produced similar results (with small variability and not to the extent as changing the reanalysis) for the turbulence diagnostics and univariate indicators. …
